HYDROCARBON-BURNER.

Application filed December 27, 1915, Serial No. 68,664. Renewed February 6, 1917.

To all whom it may concern:

Be it known that I, FRANK A. ALLINGER, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Hydrocarbon- Burners, of which the following isa specification.

This invention relates to a hydrocarbon burner, and pertains to a burner adapted for locomotives and stationaryifurnaces.

It is an object of this invention to provide a burner which will thoroughly atomize the oil and mix the latter with air so that the mixture will burn uniformly and completely without producing smoke or depositing the solid matter.

It is another object to provide a burner which will assist in, atomizing fuel by the use of free air.

A further object is to provide a burner which will eject fuel and air so that the mixture formed is spread and evenly discharged in the furnace insuring an even distribution of the heat.

A still further object is to provide a burner which is easily assembled and dis assembled for cleaning, and which will not be liable to clogging or obstruction of the passages.

I accomplish these objects by means of the embodiment of my invention illustrated in the accompanying drawing, in which:

Figure 1 is a side elevation of my improved burner.

Fig. 2 is a plan View.

Fig. 8 is a fragmentary section as seen on the line 33 of Fig. 2.

Fig. 4 is a section as seen on the line 4-4 of Fig. 1.

Fig. 5 is a fragmentary section as seen on the line 5-5 of Fig. 1.

Fig. 6 is an elevation showing the burner and its connections.

More particularly, 7 indicates the main body member of the burner which is preferably formed of cast metal substantially rectangular in outline. A head 8 is secured to the body member by bolts 9 or any other suitable means. The air, steam and oil connections are arranged to be made to the head 8. The mixture is discharged from the nozzle 10 formed on the body member.

' The body member 7 is formed with mixing Specification of I'ietters Patent.

Serial No. 146,984.

chambers consisting of tubular bores 11 and 12. which are arranged parallel to each other and extend about one-half the length of the body member 7 communicating with an expansion chamber 13 of substantially rectangular form in cross section, and hav ing a width equal to the distance across the tubular members 11 and 12. In Figs. 1 and 2 the mixing chambers are shown by dotted lines.

The head 8 is provided with bores 14 and 15 registering with the chambers 11 and 12 forming a yoke with a common bore 16 to which is connected the oil pipe 17 for feeding fuel to the burner. Pipe 17 may. be connected to the head by any convenient means such as threads. steam is indicated at 18 and extends through the body member 7, branching as indicated at 19 and 20 and communicating with the mixing chambers 11 and 12. The branches 19 and 20 are disposed substantially tangential to the cylindrical walls of the chambers 11 and 12 so that steam admitted into the chambers will have a direction eccentric thereto and will whirl. Oil which passes into the mixing chambers 11 and 12 will then be acted upon by the steam causing it to whirl and be thoroughly mixed. A bore 21 is provided in the head 8 and communicates with a steam pipe 22, indicated in Figs. 1 and 2 by dotted lines. Bore 21 registers with bore 18. y

In the body member 7 below. the expansion chamber 13 is an air chamber 23 shown by dot and dash lines in F igs. l and 2. This chamber has. an inclined bottom wall 24 so that air passing therethrough is directed upward and at an angle to the oil mixture which issues from the chamber 13. Air ports 25 and 26 extend through the body member 7 and communicate with the air chamber 23. In the head 8 is a chamber 27 from which lead ports 28 and 29 which register with ports 25 and 26 respectively. A nipple 80 is formed on the head 8 and provides means whereby the chamber 27 may be connected to an air pipe. This is necessary when the burner is used upon a locomotive in order to secure "pure air which must be taken from some particular part of the locomotive. The chamber 27 is closed by a plate 31 shown in Figs. 1 and 2. Fig. 4 shows the head 8 with the plate Patented June 5, 1917.

A small bore for removed. The plate may be secured to the 'head by bolts or any other convenient means." .Upon the delivery of oil by the pipe 17 and the delivery of steam by the pipe 22 to the burner, the steam whirls the oil carry ing it forward through the mixing cham bers l1 and 12 and into the expansion;

chamber 13. The whirling is effected in opposite directions and as the, oil passes into the expansion chamber 13 it spreads and air which spreads and produces an even and uniform heat upon the combustion of the same. r e

To insure that the air will atomize and mix with the oil it is ejected by steam. Steam ports 32 and 33 .are'disposed in the lower part of the body member 7 and be tween the air ports 25 and 26 extending into the air chamber 23, and are shown in Figs. 1 and 2 by double dot and dash lines. The

head 8 is provided with a recess 34 which registers with ports 32 and 33 and has a port 35 which connects to a steam pipe 36 for supplying steamthereto. The steam passing through the ports 32 and 33 into the-air chamber will act as an ejector and draw in air through ports 25 and 26 forcing the air outward, through the chamber 23.

In setting up the burner the pipe 17 is connected to an oil supply. Pipes 36 and 22 are controlled by valves 37 and 38, the pipes being connected to a common feeder 39 so that either the steam mixing pipe or the steam pipe for air inducing may beicu't off or regulated. If the burner is to be used.

with a locomotive an air pipe is connected intothe nipple 30. If the burner is to be used on a stationary furnace, plate 31 is re-. moved and air is taken directly into the chamber 27 What I claim is:

1. A hydrocarbon burner, comprising 'a body member formed with a tubular mixing chamber for. fuel, means for delivering steam eccentrically to said tubular chamber, an expansion chamber connected w1th sa d mixing chamber, an air-chamber with its outlet adjacent the outlet ofsaid expansion chambensaid air chamber so arranged that the air discharged therefrom will follow a path inclined andme'eting the path of fuel discharged from said expansion chamber, and steam ports connected to said air chambody member formed with complementary tubular mixin chambers arran ed aarallel to each. other, means for delivering steam eccentrically to said tubular chambers, an

expansion chamber with which said. mixing chamber connects, an air chamber adjacent said expansion chamber and having an outletdisposed contiguous to said expansion chamber outlet, and directing air at an inclinationto the fuel discharged, and steam ports connected to said air chamber to de liver steam thereinto and induce a flow of air therethrough. V v g A hydrocarbon burner, comprising a body member formed with complementary tubular mixing chambers arranged parallel to each other, means for delivering oil to said chambers, means for delivering steam ecce'ntrically to each of said mixing chambers and in opposite directions, an expansion chamber communicating with said mixing chambers, an air chamber below said expansion chamber, vsaid air chamber having a bottom wall inclined upwardly toward the expansion chamber.

5. A hydrocarbon burner, comprising a body member formed with complementary tubular mixing chambers arranged parallel to each other, means for delivering oil to said chambers, means for delivering steam eccentrically to each of said mixing chambers and in opposite directions, an expansion chamber communicating with said mixing 7 chambers, an air chamber below said expanslon chamber, said air chamber having a bottom wall inclined upwardly toward the expansion chamber, and. steam ports connected to said an" chamber to de- 7 liver steam thereto and induce a flow of air therethrough.

In witness that I claim the foregoing I have hereunto subscribed my name this 13th day'of December, 1915.
